"All the dynamics are different and easier at smaller scales."
I suppose that's why balancing a pencil upright on your fingertip is like 10 times easier than doing the same with a broomstick, right?

Based on what you are saying and tomxor in a sibling comment. Stability seems to increase with scale. Maybe it has something to do with weight, or center of mass, or a combination of the two.
I know that the longer the object you are balancing upright on your finger (or palm for something bigger than a broom), the easier it is to compensate the shifts in center of mass as it tilts. For a pencil, technically i guess it is "easier" to balance if you are a machine able to make the fine micro adjustments required.
I chose to avoid all math after high school, how dare you bring formulas into my civilized, philosophical discussion!
Your arm and hand are not great at doing many precise and gentle movements per second. With the acceleration they produce they can do many small corrections for a broom position. For a pencil, much faster and gentler corrections would be needed, and the arm + hand are too slow and imprecise to tackle that.
I think this is an issue of inertia/mass that doesn't exist so much for craft that gain and retain stability from their surroundings.
Of course, I could also be completely wrong.
